The electronic keyboard instrument 1 includes a keyboard 10, a detection circuit 11, a user interface 12, a tone generator circuit 13, an effect circuit 14, a sound system 15, a CPU 16, a timer 31, a RAM 18, a ROM 19, a data storage unit 20, a network interface 21, and the like. There is. The CPU 16 controls each unit by executing various programs stored in the ROM 19. Here, the respective units are the detection circuit 11, the user interface 12, the tone generator circuit 13, the network interface 21, and the like that are connected to the CPU 16 via the bus 22. The RAM 18 is used as a main storage device for the CPU 16 to execute various processes. The data storage unit 20 stores music data in the MIDI (Musical Instrument Digital Interface; registered trademark) format and the like. The data storage unit 20 is realized by, for example, a flash memory or the like. The timer 31 counts the remaining time up to the set time according to the instruction of the CPU 16, and outputs a signal to the CPU 16 when the remaining time becomes 0.

The keyboard 10 has a plurality of white keys and black keys corresponding to the pitch. The detection circuit 11 transmits a performance detection signal generated by detecting the movement of the keyboard 10 to the CPU 16. The CPU 16 generates MIDI performance data based on the received performance detection signal.

The tone generator circuit 13 performs signal processing on MIDI format data and outputs a digital audio signal. The effect circuit 14 outputs a digital audio signal obtained by adding an effect such as reverb to the audio signal output from the sound source circuit 13. The sound system 15 has a digital-analog converter, an amplifier, a speaker, and the like (not shown). The digital-analog converter converts the digital audio signal output from the effect circuit 14 into an analog audio signal and outputs the analog audio signal to the amplifier. The amplifier amplifies the analog audio signal and outputs it to the speaker. The speaker produces sound according to the input analog audio signal. Thus, the electronic keyboard instrument 1 produces a performance sound in response to the operation of the keyboard 10. Also, an automatic performance sound is generated based on the music data stored in the data storage unit 20. Hereinafter, producing an automatic performance sound may be referred to as reproducing.

The CPU 16 is connected to the Internet via the network interface 21 and a router (not shown), and can download music data from a content server that provides music data connected to the Internet.

The user interface 12 is arranged on the back side of the keyboard 10 when viewed from the player operating the keyboard 10. This allows the performer to play while watching the display displayed on the liquid crystal display 121.

<Outline of lesson function>
Next, the outline of the lesson function of the electronic keyboard instrument 1 will be described. The electronic keyboard instrument 1 has a plurality of types of lesson functions. Here, a lesson function for lessening the strength with which the performer presses the keyboard will be described. The "strength" of pressing the keyboard can also be expressed as "speed" of pressing the keyboard. The player strongly presses the keyboard 10 to make a loud sound. The detection circuit 11 detects the speed with which the keyboard 10 is pressed, and outputs a signal indicating the speed related to "velocity" (described later). It is said that the stronger the player presses the keyboard, the faster the key is pressed. The stronger the player presses the keyboard 10, the larger the value of “velocity” and the louder the sound volume of the performance sound produced by the sound system 15.

Now, when the player presses a key different from the example, a note with a different pitch is produced, and it is easy to notice that the player has pressed the wrong key. On the other hand, in particular, if the performer is a beginner, it is impossible to determine whether the strength of the keyboard 10 that the player is performing is strong, weak, or similar to the model. difficult. Therefore, the lesson function of the present embodiment aims to enable the player to push the keyboard 10 with three levels of strength. Here, the number of levels is limited to three so that the performer can easily determine the difference in level. In the lesson function, music data is divided into a plurality of phrases, and one phrase is instructed to be depressed a plurality of times with the same level of strength. As a result, the player can easily bring the strength of key depression closer to the target level by stacking key depressions. First, before entering a phrase, the player is instructed how strongly the player should press the sound by producing a sound at the volume to be played next. In addition, the display informs the player of the sounding timing. When the performer presses a key, the strength with which the key is pressed is displayed on the liquid crystal display 121, and then the result of comparison with the model is displayed on the liquid crystal display 121, so that the performer can determine the strength of his or her performance. Teach.

In the following description, the sound produced by the electronic keyboard instrument 1 before the next phrase is referred to as a presentation sound in order to give an image of the loudness of the sound. Further, the display performed by the electronic keyboard instrument 1 before the sounding timing is referred to as a presentation sound display in order to give an image of the loudness of the sound. Further, the display for notifying the sounding timing is called a pitch guide display. Further, in the presentation sound display, the level of strength to be displayed is called a target level, and the level of strength at which the player presses a key is called a detection level.

<Display screen>
Next, the display screen of the liquid crystal display 121 during execution of the lesson function will be described. On the display screen, a schematic plan view of the keyboard 10 (hereinafter referred to as a keyboard diagram) and a strength indicator are displayed. The pitch guide display is realized by clearly indicating the pitch to be played on the keyboard diagram. The strength indicator is an indicator that displays a strength level and the like. The presentation sound display is realized by using a strength indicator. The details of the strength indicator will be described later. Further, in the keyboard diagram, a state in which the pitch guide display is displayed is called an on state, and a state in which the pitch guide display is not displayed is called an off state. Similarly, a state where the presentation sound is displayed on the strength indicator is called an on state, and a state where the guide display is not displayed is called an off state.

<Strength indicator>
Next, the strength indicator will be described with reference to FIGS. As shown in FIG. 2, in the presentation sound display, the target level is represented by the number of “>” marks. The electronic keyboard instrument 1 displays a strong level by a display figure having eight “>” marks, a medium level by a display figure having four “>” marks, and a weak level by one “>” mark. It is displayed with the display graphic that it has. As shown in FIG. 3, in the display of the strength with which the player presses the key, the detection level is represented by the number of "■" marks. The electronic keyboard instrument 1 displays a strong level with a display graphic having eight "■" marks, a medium level with a display graphic having four "■" marks, and a weak level with one "■" mark. It is displayed with the display graphic that it has. The comparison result is displayed as shown in FIG. When the detection level is higher than the target level, the electronic keyboard instrument 1 displays a display figure indicating “strong” having “<” and “■” marks. When the detection level is within the range of the target level, a display graphic indicating "correct" having a "■" mark is displayed. When the detection level is weak with respect to the target level, a display graphic indicating “weak” having “>” and “■” marks is displayed.

<Music data>
Next, the music data will be described. The music data is data optimized for lessons. The music data of this embodiment is composed of an introduction section and a practice section. The practice section is divided into multiple phrases. The practice section is provided with a period in advance for the player to press the keys. That is, after the pitch guide display for prompting the key depression, a period for allowing the player to press the key is provided, and then the next pitch guide display is performed.

The music data includes music information and a plurality of tracks. The music information includes information such as the music name of the music data. On the track, data composed of a set of time information and an event is arranged in the order of progression of music. An event is data instructing the content of processing. The time information is data indicating a processing time. Of the plurality of tracks, one track contains lesson data, and the other tracks contain accompaniment data. The events include MIDI events “note on” and “note off”, and meta events “keyboard display on”, “keyboard display off”, “strength display on”, and “strength display off”. .. Note that "keyboard display on", "keyboard display off", "strength display on", and "strength display off" are included in the lesson track.

“Note on” is data for instructing sound generation, and “note off” is data for instructing mute. “Note number” and “velocity” are attached to “note on” and “note off”. The “note number” is data that specifies the pitch, and the “velocity” is data that represents the strength of the sound. “Keyboard display on” and “keyboard display off” are data for pitch guide display. "Note number" and the like are attached to "keyboard display on" and "keyboard display off". The time information corresponding to "keyboard display on" is data indicating sounding timing. “Strength display on” and “strength display off” are data for displaying the presentation sound. “Velocity” and the like are attached to “strength display on” and “strength display off”. Further, the time information corresponding to "strength display on" for displaying the presentation sound and the time information corresponding to "note on" for producing the presentation sound have the same timing. Further, the time information corresponding to "strength display on" for displaying the presentation sound and the time information corresponding to "note on" for pronouncing the presentation sound are the phrases indicating the key depression at the next strength. It is set, for example, one beat before the start of. An end code is included at the end of the track.

The “velocity” can take a value of 0 to 127. As mentioned above, the lesson function aims to be able to push the keyboard 10 with three levels of strength. Therefore, in the music data and the lesson function, the value of "velocity" is classified according to the level of strong/medium/weak. Specifically, the range of 1 to 42 is assigned to the weak level, the range of 43 to 84 is assigned to the medium level, and the range of 85 to 127 is assigned to the strong level. Further, as the value of “velocity” of the lesson track, 22 is used as a value indicating a weak level, 64 is used as a value indicating a medium level, and 106 is used as a value indicating a strong level.

<Function block>
Next, the functional blocks of the electronic keyboard instrument 1 will be described with reference to FIG. The electronic keyboard instrument 1 has a reading unit 41, a comparing unit 42, a performance data generating unit 43, and a display data generating unit 44, in addition to the above-described configuration. The reading unit 41, the comparison unit 42, the performance data generation unit 43, and the display data generation unit 44 are realized by, for example, the processing executed by the CPU 16.

When the performer who wants to use the lesson function operates the user interface 12 to select desired music data, the CPU 16 reads the specified music data from the data storage unit 20 and stores it in the RAM 18. The performer who wants to start the lesson function presses the "start/stop" key of the user interface 12.

When the reading unit 41 determines from the signal from the user interface 12 that the “start/stop” key has been pressed, the reading unit 41 sequentially reads the time information and the event included in the track of the music data stored in the RAM 18 from the beginning, and the timer The command corresponding to the event is output to the comparison unit 42, the display data generation unit 44, and the sound source circuit 13 at a timing according to the time information by using 31. If the event is “note on” or “note off”, the command of “note on” or “note off” is output to the comparison unit 42 and the sound source circuit 13. The tone generator circuit 13 and the effect circuit 14 perform signal processing in accordance with the input "note on" and "note off" commands and accompanying "note numbers" and "velocities". As a result, the sound system 15 produces a presentation sound (E) and an accompaniment sound (G).

If the event is “strength display on”, “strength display off”, “keyboard display on”, “keyboard display off”, the reading unit 41 reads “strength display on”, “strength display off”, “strength display on”, “strength display off”. Is output to the display data generation unit 44. When the “keyboard display on” command is input, the display data generation unit 44 creates display data for turning on the pitch guide display and outputs it to the user interface 12. Further, when a command of “keyboard display off” is input, display data for turning off the pitch guide display is created and output to the user interface 12. As a result, pitch guide display is performed on the liquid crystal display 121 (A).

In addition, when the command of “ON/OFF display” is input, the display data generation unit 44 creates display data for turning on the presentation sound display and outputs the display data to the user interface 12. Further, when the command of “display off” is input, display data for turning off the presentation sound display is created and output to the user interface 12. Specifically, the display data generation unit 44 creates display data including a display graphic of a weak level when the value of “velocity” associated with the command of “strength display on” is 22, and when the value is 64, it is a medium level. The display data including the display graphic is created, and if the value is 106, the display data including the strong level display graphic is created. As a result, the presentation sound is displayed on the liquid crystal display 121 (B).

The performance data generation unit 43 creates performance data based on the performance detection signal output from the detection circuit 11, and outputs the performance data to the comparison unit 42, the tone generator circuit 13, and the display data generation unit 44. Performance data is data composed of events and the like. The event includes “note on”, “note off”, and the like, like the music data. "Note number" and "velocity" are attached to "note on" and "note off". The tone generator circuit 13 and the effect circuit 14 perform signal processing on the input performance data. As a result, the performance sound is produced from the sound system 15 (F). The display data generation unit 44 generates display data for displaying the detection level on the strength indicator based on the input performance data and the value of “velocity”, and outputs the display data to the user interface 12. Specifically, the display data generation unit 44 generates display data for displaying a display graphic of a weak level when the value of “velocity” is in the range of 1 to 42, and the display data of the medium level when the value is in the range of 43 to 84. The display data for displaying the display graphic is generated, and if the value is in the range of 85 to 127, the display data for displaying the display graphic of the strong level is generated. As a result, the detection level is displayed on the liquid crystal display 121 (C).

The comparing unit 42 compares the “velocity” of the performance data output from the performance data generating unit 43 with the “velocity” of the music data output from the reading unit 41, and outputs the comparison result to the display data generating unit 44. To do. The display data generation unit 44 generates display data for displaying the comparison result based on the input comparison result, and outputs the display data to the user interface 12. Specifically, first, the comparison unit 42 determines whether the value of the “velocity” of the performance data is included in the weak level, the medium level, or the strong level. If the value is in the range of 1 to 42, it is determined to be a weak level, if the value is in the range of 43 to 84, it is determined to be a medium level, and if the value is in the range of 85 to 127, it is determined to be a strong level. Next, it is determined whether or not the level of the determined performance data is the same as the level indicated by the "velocity" of the music data. As described above, if the “velocity” value of the music data is 22, it is a weak level, if the value is 64, it is a medium level, and the value is a strong level. When it is determined that the level based on the performance data is the same as the level based on the music data, the comparison result corresponding to “correct” is output to the display data generation unit 44. On the other hand, when it is determined that the level based on the performance data is not the same as the level based on the music data, it is determined whether the level based on the performance data is higher than the level based on the music data. When it is determined that the level based on the performance data is higher than the level based on the music data, the comparison result corresponding to “strong” is output to the display data generation unit 44. On the other hand, when it is determined that the level based on the performance data is lower than the level based on the music data, the comparison result corresponding to “weak” is output to the display data generation unit 44. The display data generation unit 44 generates a display graphic according to the comparison result and outputs it to the user interface 12. As a result, the comparison result is displayed on the liquid crystal display 121 (D).
<Details of lesson function>

Next, details of the lesson function will be described with reference to FIG. In FIG. 6, “part” indicates the structure of music data. “Pitch guide display” indicates a period in which the pitch guide display is in the ON state by a rectangular figure. "Presentation sound display" indicates a rectangular figure for a period in which the presentation sound display is in an ON state, a period in which the detection level is displayed, and a period in which the comparison result is displayed. “Presentation sound pronunciation” indicates a period during which the presentation sound is being pronounced, with a rectangular figure. The “accompaniment” indicates a period during which the accompaniment sound is reproduced by a rectangular figure. “Key depression” indicates a period during which the player is depressing a key with a rectangular figure. In the “presentation sound display”, a rectangular figure is hatched for each of the target level “strong/medium/weak” of the presentation sound display, the detection level display period, and the comparison result display period. The distinction is shown. In “accompaniment” and “presentation sound pronunciation”, the levels of “strong/medium/weak” of the presentation sound are shown by distinguishing the hatching of rectangular figures. Further, the horizontal axis of FIG. 6 is a time axis, and the starting point is the timing when the performer presses the "start/stop" key. Note that FIG. 6 is a diagram for explaining the display and sounding procedures of the electronic keyboard instrument 1, and does not limit the relative length of the period such as the ON state period of each display.

When the "start/stop" key is pressed, the electronic keyboard instrument 1 starts playing the accompaniment. Here, since the velocity level of the first phrase is set to the strong level, the accompaniment is reproduced at the strong level. At a time t1 one beat before the first phrase in the latter half of the intro section, the electronic keyboard instrument 1 displays a strong level display figure with the strength indicator and starts to pronounce a strong level presentation sound. At time t2 after the period TD has elapsed from time t1, the presentation sound display and the presentation sound pronunciation are ended. The type of the presented sound differs depending on the velocity level. Here, the high-level sound type is a dog bark (for example, Wan), the medium-level sound type is a cat bark (for example, Meow), and the low-level sound type is a bird bark ( For example, Piyo). As a result, before entering the first phrase of the practice section, the performer can hear, for example, a "one" presentation sound and an accompaniment depending on the velocities of high, medium, and low levels, and the velocity can be changed. Can be imaged.

Next, at time t3, the display of the strong level display figure is started by the strength indicator. Next, at time t4, the pitch guide display is turned on. Next, the pitch guide display is turned off at time t5 after the period TD has elapsed from time t4. This allows the performer to know the sounding timing at which the key should be pressed by looking at the keyboard diagram while listening to the accompaniment corresponding to the velocity to be pressed. Since the period during which the pitch guide display is turned on is the period TD in the music data, the description regarding the end of the pitch guide display will be omitted. Next, at time t6, the pitch guide display is turned on again. Here, from time t7 to time t8, it is assumed that the player depresses the key at the middle level. In this case, in response to the detection circuit 11 detecting a key press, the strength indicator displays a display graphic with a medium detection level. When the display data for displaying the comparison result is output to the user interface 12, the display of the display figure corresponding to "weak" is started on the strength indicator, and the display is ended at time t9. As a result, the player can know that the strength of pressing the keys is stronger than the strength of the model, that is, the strength to be originally played. The time from time t9 to time t10 is a breathing time, for example, about 1 second. This makes it easy for the performer to visually recognize that the target level is switched.

Similarly, at the time t10 in the latter half of the first phrase and one beat before entering the second phrase, the electronic keyboard instrument 1 is a strength indicator, and the display of the middle level display figure which is the level of the second phrase and the middle level Start to pronounce the presentation sound. At time t11 after the lapse of the period TD from time t10, the presentation sound display and the sounding of the presentation sound display are ended. Next, at time t12, the music shifts from the first phrase to the second phrase, and the accompaniment is switched from the high level to the medium level reproduction. Also, the display of the middle level display figure is started by the strength indicator. Next, at time t13, the pitch guide display is turned on. Here, from time t14 to time t15, it is assumed that the player depresses the key at a strong level. In this case, the strong/weak indicator displays a display graphic having a strong detection level. At time t15, when the display data for displaying the comparison result is output to the user interface 12, the display of the display graphic corresponding to “strong” is started on the strength indicator. Next, at time t16, the pitch guide display is turned on. Here, from time t17 to time t18, it is assumed that the player depresses the key at the medium level. In this case, the strength indicator displays a display graphic with a medium detection level. When the display data for displaying the comparison result is output to the user interface 12 at time t18, the display of the display graphic corresponding to “correct” is started on the strength indicator, and the display ends at time t19.

Similarly, at time t20 in the latter half of the second phrase and one beat before the third phrase, the electronic keyboard musical instrument 1 is a strength indicator, and a weak level display graphic indicating the level of the third phrase and a weak level The pronunciation of the presentation sound is started, and the presentation sound display and the pronunciation of the presentation sound display are ended at time t11. Next, at time t22, the musical composition shifts from the second phrase to the third phrase, and the accompaniment is switched from the medium level to the weak level. In addition, the weak level indicator graphic is started to be displayed. When the reading unit 41 reads the end code of the performance data and the "start/stop" key is pressed, the electronic keyboard instrument 1 ends the reproduction of the music data.

Next, the music data and the functional blocks will be supplementarily described. In the lesson track of the music data having the content illustrated in FIG. 6, as the event of the portion corresponding to the time t3 to the time t9 of the practice section, for example, “strength display on”, “keyboard display on”, “keyboard display”. "Off", "Keyboard display on", "Keyboard display off", "Strength display off" are arranged in this order. When a plurality of “note on” are input, the tone generator circuit 13 outputs a digital audio signal corresponding to a plurality of “note on”. As a result, a plurality of sounds are duplicated and sounded by the sound system 15. On the other hand, when the display data generation unit 44 receives a “strength display on” command, a “strength display off” command, performance data, and a comparison result, which are commands relating to the display of the strength indicator, priority is given to the later arrival. To process. For example, when performance data is input at time t7, the display is switched from the target level display to the detection level display. When the comparison result is input at time t8, the display is switched to the display of the comparison result. Further, at time t9, when "strength display off" is input, the display of the strength indicator is turned off regardless of whether the display is the detection level, the comparison result, or the target level. Further, the value of “velocity” of the accompaniment track of the music data is configured in advance to correspond to the value of “velocity” of “strength display on” of the lesson track. As a result, the electronic keyboard instrument 1 can adjust the volume of the accompaniment in correspondence with "the dynamic display is on".

Here, the data storage unit 20 is an example of a storage unit. The reading unit 41, the display data generating unit 44, and the user interface 12 are an example of reproducing means. The reading unit 41, the sound source circuit 13, the effect circuit 14, the sound system 15, the display data generating unit 44, and the user interface 12 are an example of presenting means. Further, a track is an example of operation information and strength information, track time information is an example of sounding timing information and strength timing information, and a track event is an example of performance operation information and performance strength information. The keyboard 10 is an example of a performance operator.

According to the embodiment described above, the following effects are achieved.
Before performing the phrase to be played next, the performer can know the strength of key depression by displaying and pronouncing the sound to be presented by the strength indicator. Therefore, the player can practice while being aware of the strength of key depression. be able to. Moreover, since the volume of the accompaniment in the phrase is adjusted to the target level, the performer can practice while being aware of the strength of the performance operation by the volume of the accompaniment performance. Further, since the comparison result is displayed on the strength indicator, the performer can know the result of the performance performed by the performer.

[Modification]
Needless to say, the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention.
Although it has been described above that the music data includes the intro section and the practice section, the music data may include the practice section instead of the intro section. In this case, the electronic keyboard instrument 1 may be configured to include an insertion data generation unit as a functional block. Further, it is preferable that the music information of the music data includes information on the strength level used in the lesson track. For example, in the lesson track, if the value for "velocity" is the value corresponding to the medium level and the strong level, the medium level and the strong level are used as the information of the dynamic level. Make sure that the information shown is included. Before the reading unit 41 starts reading, the insertion data generation unit outputs a command of “strength display on” and “strength display off” to the display data generation unit 44 based on the strength level information of the music information, The “note-on” command is output to the tone generator circuit 13. Thereby, the presentation sound is displayed and the presentation sound is pronounced at the medium level and the strong level before the practice section is reproduced. Here, the part in which the presentation sound is displayed and the presentation sound is pronounced before the practice part is reproduced is an example of the insertion part. With such a configuration, even if the music data has no intro section, the presentation sound can be pronounced and the presentation sound can be displayed before the practice section is reproduced.

Also, I explained that the "Velocity" value of the accompaniment track of the music data was configured in advance to correspond to the "Velocity" value of "Dynamic display on" of the lesson track. Not limited. For example, a "phrase mark" for indicating phrase switching may be inserted as an event in an accompaniment track or a lesson track. In addition, the "phrase mark" is accompanied by the same "velocity" as "intensity display ON" of the same phrase. When the reading unit 41 reads the "phrase mark", the sound system 15 is instructed to sound at a volume corresponding to "velocity" associated with the "phrase mark".

Further, it may be configured to be set for each genre of music.

Further, in the above description, it is described that the presentation sound display and the presentation sound pronunciation are started one beat before the phrase starts, but the present invention is not limited to this. The time may be shorter than one beat, but if the time is set to be a long time such as "1, 2, 3", for example, the player may be ready to press a key.

The display of the strength indicator is not limited to the above. Although the configuration in which the target level, the detection level, and the comparison result are switched has been described above, all or any two of them may be displayed simultaneously. Also, the display figure is not limited to the above. For example, the target level may be displayed in characters such as strong/medium/weak, or may be displayed in a different color depending on the level. In addition, for example, the target level may be displayed without blinking, and the detection level may be displayed with blinking, so that the display form may be different depending on the type of display.

Further, in the above description, the comparison result is displayed, but the present invention is not limited to this. For example, evaluations such as “good/bad” and score display may be displayed. In this case, in addition to the evaluation of “velocity”, for example, items such as pitch and timing may be evaluated.

Although it has been described that the reading unit 41, the comparison unit 42, the performance data generation unit 43, and the display data generation unit 44 are realized by the processing executed by the CPU 16, etc., the present invention is not limited to this, and realized by a dedicated electric circuit. Alternatively, the processing executed by the CPU 16 and an electric circuit may be combined.

Moreover, although it has been described that the music data is stored in the data storage unit 20, the present invention is not limited to this. The configuration may be such that the music data is downloaded from the server via the network interface 21. The configuration of the electronic keyboard instrument 1 is not limited to the above. It may be configured to include a storage medium in which music data is stored, such as a DVD or a USB memory, and an interface for transmitting and receiving data. Further, although the network interface 21 has been described as performing LAN communication, the present invention is not limited to this. It may be configured to perform communication in accordance with another network, for example, MIDI, USB, Bluetooth (registered trademark), or the like. In this case, the music data or data stored in a communication device such as a PC, which is connected to the network, may be transmitted and the process may be executed.

Further, although the music data is described as MIDI format data, the music data is not limited to this and may be audio data, for example. In this case, it is advisable to convert the audio data into MIDI data and execute the processing. Further, although the music data has been described as having a plurality of tracks, the present invention is not limited to this, and may be composed of one track.

Further, although the electronic keyboard instrument 1 has been described as including the timer 31, the CPU 16 may execute a program to realize the timer function.

Further, in the above description, the electronic keyboard instrument 1 in which the keyboard 10 is used as the performance operator has been described as an example, but the present invention is not limited to this. For example, the present invention can be applied to a musical instrument in which a sound is generated by blowing and a sound is generated by repelling a string or a thin stick-shaped operator.
